Abstract
A multilayer ceramic composition showing good characteristics, even when electric intensity on dielectric layers is high and a stacked number of a multilayer ceramic capacitor is increased, and an electronic device thereof. Said composition comprises: a perovskite compound ABO3, and with respect to 100 moles of said compound, 0.6 or more to 1.4 or less moles of Ra2O3 in which Ra is at least one of Dy, Gd and Tb, 0.2 or more to 0.7 or less moles of Rb2O3 in which Rb is at least one of Ho and Y, and 0.2 or more to 0.7 or less moles of Rc2O3 in which Rc is at least one of Yb and Lu, in terms of each oxide, 0.6 or more to 1.6 or less moles of Mg oxide in terms of Mg, and 0.6 or more to less than 1.2 moles of Si included compound in terms of Si.
